Scientists Create Clouds Indoors

For the first time scientists have been able to create a cloud indoors and outdoors using a high-powered according to a study by the University of Geneva

.

Co-Author of the study, Scientist Jérôme Kasparian says the laser was used to squeeze water from the air in both settings.

BACKGROUND ON THESE TYPES OF STUDIES

Atmospheric scientists have been try to build artificial clouds since the 1940’s according to Science News. It says previous experiments believed water droplets needed a surface to condense on like a mirror in the bathroom during a shower. But says the study at the University of Geneva is based on the idea that when a cosmic ray strikes a sealed container filled with water vapor it leaves water droplets.

SCIENCE BEHIND THE STORY:

Why does the Cosmic Ray Work?

According to observations by scientist Charles Wilson, cosmic rays knock electrons off the water molecule leaving behind charged particles that act like specks of dust for water to congeal around says Science News.
